<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.

Answer:
En la fotofosforilación acíclica, cuando los pigmentos (clorofila) y las moléculas de agua son alcanzados por fotones (partículas de luz), existe liberación de electrones.Se llama cíclica porque los electrones son re-utilizados por la clorofila. Es una forma alternativa de producción de ATP.
